Abstract
A pressure sensor apparatus and a pressure sensor housing are provided that are capable of preventing the occurrence of frozen moisture, swelling of a gel-like coating member and damage of a pressure sensor element without accumulating moisture, oil, gasoline or the like on a protective wall even when the pressure sensor apparatus is disposed obliquely. The protective wall prevents entry of foreign matter into the pressure detection chamber, or a pressure sensor housing of the pressure sensor apparatus. The protective wall has an inclined surface that is provided with an angle θin which a second angle θis acquired between a horizontal line HL and the inclined surface that slopes downward when the pressure sensor apparatus is disposed obliquely by a first angle θwith respect to the horizontal line HL.
